Calibrating a Compton Camera in the lab

We use radioactive sources to calibrate the prototype of a Compton Camera. The Radiation Source Locator 7 (RSL7) serves as a test instrument in the decommissioning of nuclear power plants. In the current decommissioning of nuclear power plants. In the current decommissioning process, wall sections are divided into several measurement areas of 1m^2, and their gamma-ray spectra are measured individually to detect possible contaminations with different radioactive isotopes. Of particular interest here are 137Cs (662 keV) and 60Co (1173 and 1332 keV). To simplify this process by measuring whole rooms at once, we reduce the time to estimate upper limits. Together with our project partners, Hellma Materials GmbH (Jena), Brenk Systemplanung GmbH (Aachen), the Fraunhofer FKIE (Euskirchen), and the JGU Mainz, we investigate the capabilities of the RSL7 towards a new concept and improved prototype for terrestrial gamma-ray imaging.
